Mini Split Cleaning vs Replacement

Most odor and airflow issues don’t require a new unit — they need a proper deep clean.

If the unit is under 10–12 years old and only has odor, dirt, or weak airflow — clean first. Replace when compressor fails, refrigerant leaks repeatedly, or repair exceeds ~50% of replacement cost.

Clean when

  • Smell or mold is the main complaint
  • Coil visible dirty
  • Unit otherwise runs fine

Consider replace when

  • Repeated refrigerant leaks
  • Compressor failure
  • R-22 legacy equipment (rare on mini splits)
